Association of polygenic risk score with the risk of chronic lymphocytic leukemia and monoclonal B-cell lymphocytosis
2018
IF 15.132 (2017); International audience; Inherited loci have been found to be associated with risk of chronic lymphocytic leukemia (CLL). A combined polygenic risk score (PRS) of representative single nucleotide polymorphisms (SNPs) from these loci may improve risk prediction over individual SNPs. Herein, we evaluated the association of a PRS with CLL risk and its precursor, monoclonal B-cell lymphocytosis (MBL). We assessed its validity and discriminative ability in an independent sample and evaluated effect modification and confounding by family history (FH) of hematological cancers. For discovery, we pooled genotype data on 41 representative SNPs from 1499 CLL and 2459 controls from the…
Measuring deterioration in international classification of functioning domains of people with multiple sclerosis who are ambulatory.
2007
Background and PurposeMeasures to detect important effects related to physical therapy interventions must be able to detect an important change. The purpose of this study was to select the most responsive physical functioning measures for multiple sclerosis (MS) using the International Classification of Functioning, Disability and Health (ICF) as a framework.SubjectsThe participants were 120 people with MS who were ambulatory from a population-based sample.MethodsPhysical functioning was assessed by quantitative clinical measures of activities (n=5) and body functions (n=7) and by self-reported performance in self-care, mobility, and domestic life domains in the activities and participation…
Psychometric properties of measures of sociocultural influence and internalization of appearance ideals across eight countries
2020
The aim of the current study was to examine the psychometric properties of two well-established measures of sociocultural influence and internalization of the thin/low body fat ideal and muscular ideal. Data from 6272 emerging adults (68.9 % female), aged 18-30 years from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. were included in this study. Participants completed measures of pressure from mother, fathers, peers, and media, to both increase muscles and lose weight, as well as internalization of the thin/low body fat ideal and muscular ideal. Overall, support for partial invariance was found across the scales. In addition, group level differences were found between…
Role clarity, fairness, and organizational climate as predictors of sickness absence: a prospective study in the private sector.
2005
Aims: The majority of the research on the effects of the psychosocial work environment on sickness absenteeism has focused on components of job strain and social support among public sector employees without stratification by socioeconomic status. The authors examined less-studied work-related psychosocial predictors of sickness absence in the private sector by socioeconomic status. Methods: Questionnaire data on psychosocial factors at work were used to predict the rates of recorded short (1 - 3 days), long (4 - 21 days), and very long (over 21 days) sickness absences among 3,850 white- and blue-collar male and female employees in a large-scale enterprise. Multivariate Poisson regression …
Genetic and environmental influences on longitudinal changes in leisure-time physical activity from adolescence to young adulthood.
2013
The aim of this study was to estimate genetic and environmental influences on the longitudinal evolution of leisure-time physical activity habits from adolescence to young adulthood. Data were gathered at four time points, at mean ages 16.2, 17.1, 18.6, and 24.5 years. At baseline, the sample comprised 5,216 monozygotic and dizygotic twins, born 1975–1979, and, at the last follow-up point, of 4,531 monozygotic and dizygotic twins. Physical activity volume was assessed as frequency of leisure-time physical activity and participants were categorized into three groups: inactive, moderately active, and active. Genetic and environmental influences were estimated using a multivariate, longitudina…
Rapid Weight Loss Habits before a Competition in Sambo Athletes
2021
Background: Like other combat sports, sambo has competition rules that divide athletes into categories based on gender, age and weight. Athletes in combat sports often resort to rapid weight loss (RWL) methods to be more competitive in lower weight categories and gain an advantage against lighter, smaller and weaker competitors. The aim of this study was to examine the methodology implemented by two different sambo age categories, junior and senior athletes, in order to attain RWL. Methods: The sample consisted of 103 male sambo elite athletes (seniors/juniors: age 28.5 ± 4.3/18.9 ± 0.8
Men with elevated testosterone levels show more affiliative behaviors during contact with women
2012
Testosterone (T) is thought to play a key role in male–male competition and courtship in many vertebrates, but its precise effects are unclear. We explored whether courtship behaviour in humans is modulated and preceded by changes in T. Pairs of healthy male students first competed in a non-physical contest in which their T levels became elevated. Each participant then had a short, informal interaction with either an unfamiliar man or woman. The sex of the stimulus person did not affect the participants' behaviour overall. However, in interactions with women, those men who had experienced a greater T increase during the contest subsequently showed more interest in the woman, engaged in more…
Measures of Physical Functioning Predict Self-Reported Performance in Self-Care, Mobility, and Domestic Life in Ambulatory Persons With Multiple Scle…
2007
Abstract Paltamaa J, Sarasoja T, Leskinen E, Wikstrom J, Malkia E. Measures of physical functioning predict self-reported performance in self-care, mobility, and domestic life in ambulatory persons with multiple sclerosis. Objective To determine the associations between clinically measured physical functioning variables and self-reported performance in mobility, self-care, and domestic life in ambulatory persons with multiple sclerosis (MS), using the International Classification of Functioning, Disability and Health (ICF) as a framework. Design Survey study. Setting Community setting in Finland. Participants A population-based sample of 120 ambulatory persons with MS (30 men, 90 women) wit…
Relative and absolute socioeconomic inequality in smoking: time trends in Germany from 1995 to 2013
2020
Abstract Purpose This study aimed to investigate time trends in relative and absolute socioeconomic inequality in smoking prevalence in Germany using several indicators for socioeconomic position. Methods We conducted a repeated cross-sectional study using representative samples of the German population aged between 25 and 64 years in 1995, 1999, 2005, 2009, and 2013 (n = 857,264). Socioeconomic position was measured by indicators for income, education, and occupation. Relative and absolute socioeconomic inequalities were estimated with the regression-based relative index of inequality and the slope index of inequality, respectively. Trends in inequalities were estimated with interaction te…
Physical Activity, Sleep, and Symptoms of Depression in Adults - Testing for Mediation
2019
Abstract Purpose: Physical activity, sleep problems, and symptoms of depression contribute to overall well-being. The factors are reciprocally associated, but the nature of these associations remains unclear. The present study examined whether sleep problems mediated the association between physical activity and depressive symptoms. Methods: The eligible population (n = 3596) consisted of adults from the ongoing, population-based Cardiovascular Risk in Young Finns Study started in 1980. Participants’ leisure-time physical activity was assessed with physical activity index (2007) and sleep problems with Jenkins’ Sleep Questionnaire in 2007 and 2011. Depressive symptoms were measured using mo…
